Alrighty I think I’ve got a good idea on how to address this issue, though it’s going to take a bit of work. I’m going to postpone it until some of the more pressing bugs are fixed up, but I’ll make it happen

This has happened in all of my correspondence games this year. I use Chrome. My rough observation is that it does not seem to depend on time (as a refresh would) but as a result of a very large number of variations. In other words, it seems like it reaches a default limit and resets.

I find my analysis gets reset whenever I refresh the page, like when playing a correspondence game. I get why this might be the case (analysis stored in browser session, not in game), especially since SGF don’t seem to store variations/branches in a single file.

The phenomenon that I think we are talking about, as least in my case, is unsaved variations in the game window, which spontaneously disappear after awhile, not due to refreshing or leaving the window. It may well be an issue peculiar to Chrome.
